Abstract: A method for enhancing the performance of an ECR plasma source, relating to the application field of low-temperature plasma sources. The original source of space electrons is a small quantity of free electrons in a resonance region of existing ECR, electrons generated by gas ionization are source of the electrons when plasma discharge is formed, the electron density is limited when equilibrium is achieved, and the improvement of plasma parameters is restricted. On the basis of an existing ECR plasma source, the method uses a thermionic cathode (5) to generate a lot of thermal electrons, and the thermal electrons enter a resonance space under the control of an electric field passing through the resonance region, so that the electron density of the resonance region is improved. Because the electron density of the resonance region is improved, the ECR ionization efficiency is further enhanced, and performance indexes such as the beam density of the ECR plasma source are improved.
